In 2000, I ordered a new 2001 Diplomat LE to full-time in. Did it for 10 years (that was enough). I had a trusted truck tire dealer, who also had a diesel pusher. When I bought new tires, he talked me into the balancing beads. We left on a long trip out west (from Tennessee). I have a CO2 tank that I use to air my tires and was using it at a campsite during the trip. I noticed that air was escaping from the valve stem and I couldnt stop it. I quickly put the alligator valve stem cover back on and it seemed to quit. I called Coach Net and told them I thought the valve stem was faulty. Coach Net came out, he agreed and replaced the valve stem and aired all my tires. I stopped to get fuel and noticed that the front, passenger tire was nearly flat, fortunately the truck stop was able to help me. Then, I had the same situation when airing tires in another campground. I was in a mess.
I called my tire guy and he told me that the wrong size beads had been used and were getting wedged in the valve stem. I told him that I wanted those beads GONE and he agreed to reimburse me the cost of dismantling each tire and removing the beads. I was in Arizona and he was in Tennessee.
Now, I never had the rear tires balanced, but THINK I did the front, not sure why; it was a long time ago. With the tires not being balanced, I never experience any vibration or abnormal wear.
I finally sold the DipLE and now have a 31' Phoenix Cruiser. It is so much easier in every aspect of motorhome ownership. We do miss the room, but totally enjoy the PC. Keep in mind that at 72, I no longer want the "hassles" of a diesel pusher. Your mileage may vary. I still learn from and enjoy this forum. Finally, I am not a charter member here, but close. I had many "disputes" with Bill D, he never realized he was no longer a colonel in the Air Force. 😇😊
